Unveiling the Mystery of Cloudy Urine: Be Aware of the Threat of Chyluria

So, aside from physiological phenomena, what diseases in clinical practice can cause cloudy urine?

1. Prostatitis: Cloudy urine may sometimes indicate chronic prostatitis. When the prostate is congested and swollen, and secretions increase, a small amount of white fluid may frequently flow from the urethra in the morning, at the end of urination, or during defecation. This is called prostatic fluid discharge or dribbling, and is a reference indicator for diagnosing chronic prostatitis.

2. Gonorrhea or non-gonococcal urethritis: If there is a large amount of white discharge from the urethra, accompanied by obvious symptoms such as urinary urgency, frequency, and pain, and a history of unprotected sex, it is most likely gonococcal urethritis. If there is less discharge but obvious urinary tract irritation and a history of unprotected sex, it may be non-gonococcal urethritis. Both of these conditions are sexually transmitted diseases and should be treated promptly with proper medical care.

Many diseases that can cause cloudy urine cause headaches for men, but chyluria is particularly dreaded by them.

Chyluria is named for its cloudy urine that resembles milk, swill, or soy milk. The chyle excreted in the urine is actually a type of white urine, caused by the reflux of protein and fat chyle from the urine sample into the urine due to the lymphatic vessels being blocked by the lymph fluid contained in the urine. It appears milky white in varying degrees and is most common in men aged 30 to 60.

In Traditional Chinese Medicine (TCM), the pathogenesis of chyluria is considered closely related to the spleen and kidneys. It is attributed to spleen yang deficiency, insufficient qi, damp-heat accumulation in the lower body, and kidney yin deficiency. TCM believes that the spleen is the source of vital energy, and the kidneys are the storehouse of essence. Spleen deficiency leads to impaired transformation and transportation, while kidney deficiency results in dysfunction of storage, leading to the leakage of essence, where the clear and turbid substances are not separated and descend through the bladder, resulting in cloudy urine that resembles milk or fat.

Chyluria is a dreaded condition primarily because it is almost always caused by parasites, and it is a common complication in both the acute and chronic phases of filariasis infection. Approximately 2% to 10% of filariasis-infected individuals develop chyluria, typically occurring 3 to 5 years after infection, and is most common in men aged 20 to 40. The recurrence rate of chyluria is high; overexertion, alcohol consumption, high-fat meals, and colds or fevers can all trigger or worsen it. Patients may experience unilateral or bilateral lower back pain or dull aches. Sometimes, chyle and blood clots can obstruct the ureter, causing renal colic; if the urethra is obstructed, difficulty urinating or urinary retention may occur. Long-term, recurrent chyluria can lead to symptoms of malnutrition such as fatigue, weight loss, edema, and anemia.

In addition, non-parasitic diseases, such as tuberculosis and malignant tumors, can also cause damage or blockage to the retroperitoneal lymphatic vessels and lymph nodes, leading to chyluria, but this is generally rare.

Therefore, if men find their urine to be cloudy, milky white, or like rice water, they should not ignore it. They should immediately go to the hospital for further blood and urine tests. If necessary, lymphangiography and cystoscopy can be performed. If filariasis is confirmed in the blood or urine, drug treatment should be started immediately.

In daily life, avoid excessive consumption of spicy, greasy, and soy products; a light diet is recommended, with moderate intake of vegetables, mushrooms, lotus seeds, black fungus, yams, and fruits such as cantaloupe, watermelon, pears, apples, coconuts, and pineapples. Paying attention to rest and avoiding overwork also has good health benefits for cloudy urine; men may wish to try it.

Blood in urine must be investigated thoroughly.

"The sunset glows and the lone wild goose fly together; the autumn waters blend with the vast sky." This timeless masterpiece from Wang Bo's "Preface to the Pavilion of Prince Teng" has evoked endless reverie among countless literati.

Azure skies and clear waters meet seamlessly, creating a breathtaking panorama. Crimson sunset clouds descend from above, while a lone wild goose soars from below, their vibrant colors complementing each other. This magnificent scene, seemingly shimmering on the vast expanse of clear water, paints a stunning picture of vibrant colors and harmonious composition, offering future generations a magnificent visual feast.

When asked about the source of its powerful artistic appeal, some say it lies in the clever use of strong color contrast, which maximizes the vividness of both colors, making the whole picture look exceptionally bright and beautiful.

It would be a grave mistake to assume that a touch of crimson amidst a light and elegant aesthetic is always a symbol of beautiful art. Sometimes, the "splendid art" emanating from the body may be a warning sign of disease, such as hematuria.

Whether in outpatient examinations or routine physical examination reports, we often see urine routine tests showing BLD (+/++/+++) or traces of more than 5 red blood cells per high-power field under a microscope. We also hear descriptions such as recent urine being like meat-washing water, bloody, or containing blood clots in the urine. This is what is known as "hematuria".

So, what exactly is "hematuria," and is it a disease?
